IMPROVEMENT IN MlTERlNG-MACHINES.

Specification forming part of Letters Patent No. 154,234, dated August 18, 1874; application filed January 10,1874.

To all'whom it may concern:

Be it known that I, EDWIN EVERETT, of Andover, in the county of Allegany and State of New York, have invented a new and useful Improvement in Mitering-Machines, of which the following is a specification:

Figure l is a vertical longitudinal section of my improved machine, taken through the line .70 ac, Fig. 2. Fig. 2 isa top view of the same.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described, and then pointed out in the claim.

A represents a rectangular frame of suitable size, formed of two side bars and two end bars securely framed to each other, or other'- wise firmly attached at their ends. In the inner edges of the side bars of the frame A are formed longitudinal grooves to receive tongues formed upon the side edges of the strip B, which is fittedlinto the space between said side bars, and is made shorter than they are, so that it may have alongitudinal movement upon them. To the under side of the forward end of the sliding strip B is attached a screw, 0. which passes out through the for-,

ward-end bar of the frame A, and has a handnut, c, screwed upon its outer end, so that, by turning the said nut c, the strip B may be moved forward'and back in the frame A. To the forward part of the upper side of the sliding strip B is attached a square block, D, in an accurate diagonal position, so that its sides may be at an angle of forty-five degrees-(45 with the length of the said strip B. To the forward corners of the frame A are attached triangular blocks E, the inner edges of which are exactly parallel with the forward edges of the square block D. To the upper side of the block D are attached the lower edges of two parallel strips, F, which are also'parallel with, and equally distant from, the central line of the saw-plate, by bolts J. The blocks are made perfectly true, and of such a thickness as, when clamped to the saw-plate,to fit accurately into the space between the blocks or strips F, and thus cause the saw to work exactly in the same line, and without any vibration, making a smooth true cut, so that, when the beveled ends of. the molding-strips are brought together, they will form a close joint without any dressing.

The strips of lIiOldlIlg are clamped, while being sawed, between the forward inclined edges of the block D and the inclined edges of the triangular blocks E by tightening the nut 0 upon the screw G, and, when sawed, the two inclined ends of the molding are brought together and clamped in the same Way, and held securely, While being nailed, rendering the use of a vise unnecessary for this purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is l The combination, iua mitenmachine, with sliding strip B, of the triangular block D, blocks E, and parallel strips F F, as and for the purpose described.

EDWIN EVERETT.
